To all whom it may concern: 7

Be it known that I, WILLIAM a citizen of the UnitedState'gresidmg at Canyon City, in the county of Grant and 7 brush grubber constructed in accordance with the invention; and

Fig. 2 is a side elevation thereof.

Like numerals designate corresponding parts in both of the figures of the drawing.

By referring to the drawing it will be seen that my improved sage brush grubber is formed principally of two beams, one a main longitudinal beam 5 and the'other an angular beam 6. The beam 6 may lie at any suitable angle with respect to beam 5 but it is preferably disposed at a forty-five degree angle, and it is joined to the-beam 5 with a ship lap joint of such strength and rigidity as to enable the beam 6 to resist the tendency for it to swing'into alinement with the beam I 5 whenthe structure is in use.

The beam 6 carries a cutting blade 7 that extends entirely along its lower edge and is united to the beam 5 at 8. The nose of the beam 5 is indented as indicated at 9 and car-v ries a blade 10 which extends across its lower edge. Both the blades 7 and 10 project slightly'below the level of the beams 6 and 5 and the lower edges of these blades project forward to a limited extent and in such manner that the action is more of a scraping action than of a cutting action. The beam 6 carries a hook 11 which constitutes a point of attachment for a chain 12 the other end of which may be passed around the indented portion of the nose of the beam 5 and through an opening 13', this chain constituting means by which the structure may be drawn bodily along the round.

I am well aware of t e fact that it has heretofore been proposed toemploy various types of V shaped structures for use as road Specification of Letters am.

graders v and 'the like, but careful considera- ;tion"v\"ill.'show sthat the structure herein shown and described possesses. oints of novelty and [advantage not possessed structure with which I' am familiar. In the by iany first place it is to be particularly noted that w the beam 5 is of substantially the same thickness and width throughout itslength: and v that the same is true of the beam 6. This causes the main beam to lie flat-upon the surface of the ground. This main beam carto hold the beam against lateral'movement.

v The armoringof the nose of the main beam 5 by the blade lO'which' extends at an angle lies a vertical blade 14 depending fromits under side adjacent its rear end and acting causes the nose of the mainbeam to not only exercise a clearing function, but keepsthe nose down to; the work; In other words,

this inclined blade prevents lifting of the nose of the structure, that would otherwise occur.

' It is to be understood that the invention is. not limited to the precise construction set forth but that it includes within itspurview whatever changesfairly come within either the scope or the spiritof the appended claims. 7

" Having described -my invention, what claim is-- 1. A'struoture of the character described comprising a longitudinally extending main beam adapted to lie and travel directly upon the ground, a beam secured thereto and extending at an angle therefrom, and blades disposed along the lower edge of the last named beam and across the nose of the main beam, the nose of the main beam lying at substantially the angle of the second named beam. I

2. A structure of the character described comprising a longitudinally extendingmain beam, an angularly dlsposed beam secured thereto by a ship lap joint to thereby cause both of said beams to lie in substantially the same plane, the bottoms of both of said beams being adapted to liedirectly upon and travel in contact with the ground, the front end of the main beam lying in substantial par-allelism with the angularly disposed beam, a

blade having its lower edge forwardly directed secured alongthe edge of the angularly disposed beam and extending slightly therebeloii and a blade secured upon the for- Ward end of the main beam and conforming to the direction thereof and slightly therebelow, the last nam ing forwardly inclined.

3. A structure of the character described comprising a longitudinally extending main beam, an a-ngularl'y disposed beam secured thereto by a ship lap jointto thereby cause both of said beams to lie in'substantially the same plane,- the bottoms 50f, both of said beams being adapted to lie; directly upon and trayel in contact With the ground; the frontend; of the main beani lying': in sub- ,j stantial parallelism with the; angular-1y disej ct blade bev posed beainya blade having its' loiver edge forwardl directed securedalong the edge of the ang'u 'arly disposed and extending 'blade'being forwardly inclined,-and a blade carried. by the main beam adjacent the reait end thereof and projecting therebelow in a vertical plane and lying o in longitudinalalinen ent therewith.
